Definition of the problem The umbrella term “explicability” refers to the reduction of opacity of artificial intelligence (AI) systems. These efforts are challenging for medical AI applications because higher accuracy often comes at the cost of increased opacity. This entails ethical tensions because physicians and patients desire to trace how results are produced without compromising the performance of AI systems. The centrality of explicability within the informed consent process for medical AI systems compels an ethical reflection on the trade-offs. Which (...) levels of explicability are needed to obtain informed consent when utilizing medical AI? Arguments We proceed in five steps: First, we map the terms commonly associated with explicability as described in the ethics and computer science literature, i.e., disclosure, intelligibility, interpretability, and explainability. Second, we conduct a conceptual analysis of the ethical requirements for explicability when it comes to informed consent. Third, we distinguish hurdles for explicability in terms of epistemic and explanatory opacity. Fourth, this then allows to conclude the level of explicability physicians must reach and what patients can expect. In a final step, we show how the identified levels of explicability can technically be met from the perspective of computer science. Throughout our work, we take diagnostic AI systems in radiology as an example. Conclusion We determined four levels of explicability that need to be distinguished for ethically defensible informed consent processes and showed how developers of medical AI can technically meet these requirements.

Recent years have witnessed intensive efforts to specify which requirements ethical artificial intelligence (AI) must meet. General guidelines for ethical AI consider a varying number of principles important. A frequent novel element in these guidelines, that we have bundled together under the term explicability, aims to reduce the black-box character of machine learning algorithms. The centrality of this element invites reflection on the conceptual relation between explicability and the four bioethical principles. This is important because the application of general ethical (...) frameworks to clinical decision-making entails conceptual questions: Is explicability a free-standing principle? Is it already covered by the well-established four bioethical principles? Or is it an independent value that needs to be recognized as such in medical practice? We discuss these questions in a conceptual-ethical analysis, which builds upon the findings of an empirical document analysis. On the example of the medical specialty of radiology, we analyze the position of radiological associations on the ethical use of medical AI. We address three questions: Are there references to explicability or a similar concept? What are the reasons for such inclusion? Which ethical concepts are referred to? (shrink)

The field of of imprecise probability has matured, in no small part because of Teddy Seidenfeld’s decades of original scholarship and essential contributions to building and sustaining the ISIPTA community. Although the basic idea behind imprecise probability is (at least) 150 years old, a mature mathematical theory has only taken full form in the last 30 years. Interest in imprecise probability during this period has also grown, but many of the ideas that the mature theory serves can be difficult to (...) apprehend to those new to the subject. Although these fundamental ideas are common knowledge in the ISIPTA community, they are expressed, when they are expressed at all, obliquely, over the course of years with students and colleagues. -/- A single essay cannot convey the store of common knowledge from any research community, let alone the ISIPTA community. But, this essay nevertheless is an attempt to guide those familiar with the basic Bayesian framework to appreciate some of the elegant and powerful ideas that underpin the contemporary theory of lower previsions, which is the theory that most people associate with the term ‘imprecise probabilities’.

In this paper I consider the prospects for a skeptical version of infallibilism. For the reasons given above, I think skeptical invariantism has a lot going for it. However, a satisfactory theory of knowledge must account for all of our desiderata, including that our ordinary knowledge attributions are appropriate. This last part will not be easy for the infallibilist invariantist. Indeed, I will argue that it is much more difficult than those sympathetic to skepticism have acknowledged, as there are serious (...) problems with regarding paradigmatic, typical knowledge attributions as loose talk, exaggerations, or otherwise practical uses of language. So, I do not think the pragmatic story that skeptical invariantism needs is one that works without a supplemental error theory of the sort left aside by purely pragmatic accounts of knowledge attributions. In its place, I will offer a compromise pragmatic and error view that I think delivers everything that skeptics can reasonably hope to get. (shrink)

“I know that p but it is possible that not-p” sounds contradictory. Some philosophers, notably David Lewis, have taken this as evidence that knowledge requires infallibility. Others have attempted to undermine that inference by arguing that there is a plausible pragmatic explanation of why such sentences sound odd, and thus do not undermine fallibilism. I argue that the proffered pragmatic explanations fail and I raise challenges for any possible pragmatic explanation of the character of concessive knowledge attributions. It is reasonable (...) to conclude that concessive knowledge attributions are genuine contradictions. (shrink)

‘Irony,’ says Quintilian, is that figure of speech or trope ‘in which something contrary to what is said is to be understood’ . His formula has stood the test of time. It passes intact into Dr Johnson's dictionary . It survives virtually intact in ours:Irony is the use of words to express something other than, and especially the opposite of, [their] literal meaning.

In The Decline of the West Spengler puts forward a type of philosophical anthropology, an account of the structures of human experiential consciousness and a method of “physiognomic” analysis, which I argue has dimensions that can be understood as akin to existential phenomenology. Humanity, for Spengler, is witness to the creative flux of “Becoming” and constructs a world of phenomena bounded by death, underpinned by the two prime feelings of dread and longing and structured by the two forms of Destiny (...) (Time) and Direction (Space). Human existence, Spengler argues, is future-directed and open in the sense that there is a certain degree of freedom in the ways in which humanity can actualize its existential possibilities. In the course of elaborating the existential implications of this future-orientation, Spengler introduces the concept of care (Sorge), the fundamental experiential structure. (shrink)

This book chapter represents one of the engagements between Catholic and Wesleyan philosophers at the 2008 Wesleyan Philosophy Society. The issue of what precisely "Wesleyan philosophy" would mean and comprise can be usefully illuminated by comparison with the positions and issues that were raised and discussed by Catholic scholars during the 1930s Christian philosophy debates in France, which included Etienne Gilson, Maurice Blondel, Jacques Maritain, and Gabriel Marcel. We also discuss how the thought on a contemporary Catholic philosopher Adriaan Peperzack, (...) specifically on affectivity, can be brought into comparison with that important theme in Wesleyan philosophy.

Advances in artificial intelligence and neuroscience claim to have begun to undermine the assumptions of the arts and educational theory community by explaining consciousness through either a reduction to mathematical functionalism or an excrescence of brain biology. I suggest that the worldview behind such reductionism is opposed to the worldview assumed by many educational practitioners and theorists. I then go on to outline a few common positions taken in the burgeoning field of consciousness studies that suggest that—though many attributes of (...) consciousness have been identified and explained—individual consciousness itself remains as much of an enigma to scientists as to the rest of us who experience it. However, I do suggest the necessity of intersubjectivity for conscious evolution. (shrink)

Purpose: The method of diagnosing diabetic retinopathy (DR) through artificial intelligence (AI)-based systems has been commercially available since 2018. This introduces new ethical challenges with regard to obtaining informed consent from patients. The purpose of this work is to develop a checklist of items to be disclosed when diagnosing DR with AI systems in a primary care setting. -/- Methods: Two systematic literature searches were conducted in PubMed and Web of Science databases: a narrow search focusing on DR and a (...) broad search on general issues of AI-based diagnosis. An ethics content analysis was conducted inductively to extract two features of included publications: (1) novel information content for AI-aided diagnosis and (2) the ethical justification for its disclosure. -/- Results: The narrow search yielded n = 537 records of which n = 4 met the inclusion criteria. The information process was scarcely addressed for primary care setting. The broad search yielded n = 60 records of which n = 11 were included. In total, eight novel elements were identified to be included in the information process for ethical reasons, all of which stem from the technical specifics of medical AI. -/- Conclusions: Implications for the general practitioner are two-fold: First, doctors need to be better informed about the ethical implications of novel technologies and must understand them to properly inform patients. Second, patient's overconfidence or fears can be countered by communicating the risks, limitations, and potential benefits of diagnostic AI systems. If patients accept and are aware of the limitations of AI-aided diagnosis, they increase their chances of being diagnosed and treated in time. (shrink)

Pereira’s “The Projective Theory of Consciousness” is an experimental statement, drawing on many diverse sources, exploring how consciousness might be produced by a projective mechanism that results both in private selves and an experienced world. Unfortunately, pulling together so many unrelated sources and methods means none gets full attention. Furthermore, it seems to me that the uncomfortable breadth of this paper unnecessarily complicates his project; in fact it may hide what it seeks to reveal. If this conglomeration of diverse sources (...) and methods were compared to trees, the reader may feel like the explorer who cannot see the forest for the trees. Then again, it may be the author who is so preoccupied with foreground figures that the everpresent background is ultimately obscured. (shrink)

This paper argues that Oswald Spengler has an innovative philosophical position on the nature and interrelation of mathematics and science. It further argues that his position in many ways parallels that of Martin Heidegger. Both held that an appreciation of the mathematical nature of contemporary science was critical to a proper appreciation of science, technology and modernity. Both also held that the fundamental feature of modern science is its mathematical nature, and that the mathematical operates as a projection that establishes (...) in advance the manner in which an object will present itself. They also assert that modern science, mathematics and metaphysics all have their roots in the ‘mathematical’, whose essence is itself nothing numerical. (shrink)

The desirable gambles framework offers the most comprehensive foundations for the theory of lower pre- visions, which in turn affords the most general ac- count of imprecise probabilities. Nevertheless, for all its generality, the theory of lower previsions rests on the notion of linear utility. This commitment to linearity is clearest in the coherence axioms for sets of desirable gambles. This paper considers two routes to relaxing this commitment. The first preserves the additive structure of the desirable gambles framework and (...) the machinery for coherent inference but detaches the interpretation of desirability from the multiplicative scale invariance axiom. The second strays from the additive combination axiom to accommodate repeated gambles that return rewards by a non-stationary processes that is not necessarily additive. Unlike the first approach, which is a conservative amendment to the desirable gambles framework, the second is a rad- ical departure. Yet, common to both is a method for describing rewards called discounted utility. (shrink)

In this paper the system IL for relative interpretability is studied.

Spengler’s work is typically represented as speculative philosophy of history. However, I argue that there is good reason to consider much of his thought as preoccupied with existential and phenomenological questions about the nature and ends of human existence, rather than with history per se. In this paper I consider Spengler’s work in comparison with Heidegger’s history of Being and analysis of technological modernity. I argue that Spengler’s considerable proximity to much of Heidegger’s thought compels us to reconsider the nature (...) and scope of Spengler’s philosophical project. (shrink)

My paper was commissioned by Journal of Philosophy to provide a piece adequately explaining the significance of the Lacanian Mirror stage within Lacan's larger work. -/- I focus on the transition from the mirror stage to the incorporation of the subject into the symbolic order. I argue that the mirror stage is transitional and that its significance lies in what of it is incorporated into and transformed within the more complex structures of the subject and the unconscious. -/- Implicit in (...) my claim is that "lacanian" theories which hypostatize the mirror stage into a determinate structure of adult consciousness are misinterpreting Lacan. I use Seminars 1 and 2 to make fuller sense the mirror stage as presented in his Ecrits. (shrink)

Report submitted by Gregory B. Sadler, Pilot Project Coordinator to Sonya Brown, WAC Activity Director, Fayetteville State University, June 28 2011. -/- A Pilot program focused on improving student performance in carrying out Close Readings in humanities-based discipline courses was developed and implemented under the auspices of Writing Across the Curriculum and Title III at Fayetteville State University in Winter and Spring 2011. Five faculty were involved in the Pilot, myself as the coordinator, and four other faculty from four (...) different disciplines as participants. -/- The central idea behind the Pilot was that by focusing on the lower-order skills which are scaffolded as components into the higher-order activity of Close Reading of texts, and redesigning courses to emphasize development of these lower-order skills, student performances in Close Readings would also be improved. This did turn out to be the case. Most of the supporting data is qualitative rather than quantitative. -/- It is recommended that similar activities be continued, but that participating faculty be required to provide much more prescriptively structured and detailed assessment data and information about their course design.

In The Decline of the West, Spengler argues that cultures have lifecycles. Although he warns that the end of Faustian (western) culture is nigh, Spengler suggests that the death of the culture might be forestalled if a rapprochement can be brought about between the technologized powers of Reason and the remains of cultural life. This portrayal of Reason as a salvific force seems to contradict Spengler’s typical depiction of Reason as a violent anti-cultural force. This paper reconstructs Spengler’s account of (...) Reason as both killer and preserver of western culture and argues that in both roles it remains inherently violent. (shrink)

In this paper, I offer an analysis of the radical disagreement over the adequacy of string theory. The prominence of string theory despite its notorious lack of empirical support is sometimes explained as a troubling case of science gone awry, driven largely by sociological mechanisms such as groupthink (e.g. Smolin 2006). Others, such as Dawid (2013), explain the controversy by positing a methodological revolution of sorts, according to which string theorists have quietly turned to nonempirical methods of theory assessment given (...) the technological inability to directly test the theory. The appropriate response, according to Dawid, is to acknowledge this development and widen the canons of acceptable scientific methods. As I’ll argue, however, the current situation in fundamental physics does not require either of these responses. Rather, as I’ll suggest, much of the controversy stems from a failure to properly distinguish the “context of justification” from the “context of pursuit”. Both those who accuse string theorists of betraying the scientific method and those who advocate an enlarged conception of scientific methodology objectionably conflate epistemic justification with judgements of pursuit-worthiness. Once we get clear about this distinction and about the different norms governing the two contexts, the current situation in fundamental physics becomes much less puzzling. After defending this diagnosis of the controversy, I’ll show how the argument patterns that have been posited by Dawid as constituting an emergent methodological revolution in science are better off if reworked as arguments belonging to the context of pursuit.

In this paper, I defend a new theory of normative reasons called reasons as good bases, according to which a normative reason to φ is something that is a good basis for φing. The idea is that the grounds on which we do things—bases—can be better or worse as things of their kind, and a normative reason—a good reason—is something that is just a good instance of such a ground. After introducing RGB, I clarify what it is to be a (...) good basis, and argue that RGB has various attractive features: it has intuitive implications, makes good sense of the weights of reasons, and attractively explains the relationship between normative reasons and motivating reasons. I then briefly defend the view from objections and compare it to rivals. Finally, I sketch two possible implications of RGB: some kind of constitutivism, according to which the norms that govern us are explained by the nature of agency, and second, the claim that agents who do things for reasons generally do them for good reasons.

The theory of lower previsions is designed around the principles of coherence and sure-loss avoidance, thus steers clear of all the updating anomalies highlighted in Gong and Meng's "Judicious Judgment Meets Unsettling Updating: Dilation, Sure Loss, and Simpson's Paradox" except dilation. In fact, the traditional problem with the theory of imprecise probability is that coherent inference is too complicated rather than unsettling. Progress has been made simplifying coherent inference by demoting sets of probabilities from fundamental building blocks to secondary representations (...) that are derived or discarded as needed.

In this paper, I explain the curious role played by the Argument from Absolute Terms in Peter Unger's book Ignorance, I provide a critical presentation of the argument, and I consider some outstanding issues and the argument’s contemporary significance.

In this article, I will provide a critical overview of the form of non-deductive reasoning commonly known as “Inference to the Best Explanation” (IBE). Roughly speaking, according to IBE, we ought to infer the hypothesis that provides the best explanation of our evidence. In section 2, I survey some contemporary formulations of IBE and highlight some of its putative applications. In section 3, I distinguish IBE from C.S. Peirce’s notion of abduction. After underlining some of the essential elements of IBE, (...) the rest of the entry is organized around an examination of various problems that IBE confronts, along with some extant attempts to address these problems. In section 4, I consider the question of when a fact requires an explanation, since presumably IBE applies only in cases where some explanation is called for. In section 5, I consider the difficult question of how we ought to understand IBE in light of the fact that among philosophers, there is significant disagreement about what constitutes an explanation. In section 6, I consider different strategies for justifying the truth-conduciveness of the explanatory virtues, e.g., simplicity, unification, scope, etc., criteria which play an indispensable role in any given application of IBE. In section 7, I survey some of the most recent literature on IBE, much of which consists of investigations of the status of IBE from the standpoint of the Bayesian philosophy of science. (shrink)

Sumantra Ghoshal’s condemnation of “bad management theories” that were “destroying good management practices” has not lost any of its salience, after a decade. Management theories anchored in agency theory (and neo-classical economics generally) continue to abet the financialization of society and undermine the functioning of business. An alternative approach (drawn from a more classic institutional, new ecological, and refocused ethical approaches) is reviewed.

_Theurgy and the Soul_ is a study of Iamblichus of Syria, whose teachings set the final form of pagan spirituality prior to the Christianization of the Roman Empire. Gregory Shaw focuses on the theory and practice of theurgy, the most controversial and significant aspect of Iamblichus's Platonism. Theurgy literally means "divine action." Unlike previous Platonists who stressed the elevated status of the human soul, Iamblichus taught that the soul descended completely into the body and thereby required the performance of (...) theurgic rites—revealed by the gods—to unite the soul with the One. Iamblichus was once considered one of the great philosophers whose views on the soul and the importance of ritual profoundly influenced subsequent Platonists such as Proclus and Damascius. The Emperor Julian followed Iamblichus's teachings to guide the restoration of traditional pagan cults in his campaign against Christianity. Although Julian was unsuccessful, Iamblichus's ideas persisted well into the Middle Ages and beyond. His vision of a hierarchical cosmos united by divine ritual became the dominant world view for the entire medieval world and played an important role in the Renaissance Platonism of Marsilio Ficino. Even Ralph Waldo Emerson wrote that he expected a reading of Iamblichus to cause a "revival in the churches." But modern scholars have dismissed him, seeing theurgy as ritual magic or "manipulation of the gods." Shaw, however, shows that theurgy was a subtle and intellectually sophisticated attempt to apply Platonic and Pythagorean teachings to the full expression of human existence in the material world.

Oswald Spengler is best known as a philosopher of history. However, one can trace in volume one of his The Decline of the West a sustained consideration of philosophical issues pertaining to the nature and practice of science that I suggest can be considered to be a philosophy of science. Not only has Spengler’s philosophy of science been largely overlooked, so too has its peculiar fictionalist character. By elaborating on the fictionalist character of Spengler’s scientific views I shall consider his (...) work in comparison with that of Hans Vaihinger, a contemporary of Spengler and noted fictionalist with regards to science. This comparison not only supports my interpretation of Spengler’s philosophy of science as fictionalist, it also throws into relief the numerous affinities between the thought of two philosophers who are not usually associated, in particular with regards to their accounts of the origins of science in the structures of human consciousness. This fictionalist affinity in turn suggests the need for a wholesale reappraisal of Spengler’s philosophical outlook. (shrink)

Ancient philosophical schools developed and discussed perspectives and practices on the emotion of anger useful in contemporary philosophical practice with clients, groups, and organizations. This paper argues the case for incorporating these insights from four main philosophical schools (Platonist, Aristotelian, Epicurean, and Stoic) sets out eight practices drawn from these schools, and discusses how these insights can be used by philosophical practitioners with clients.

Philosophy of technology was not initially considered a consolidated field of inquiry. However, under the influence of sociology and pragmatist philosophy, something resembling a consensus has emerged in a field previously marked by a lack of agreement amongst its practitioners. This has given the field a greater sense of structure and yielded interesting research. However, the loss of the earlier “messy” state has resulted in a limitation of the field’s scope and methodology that precludes an encompassing view of the problematic (...) issues inherent in the question of technology. It is argued that the heterodox disunity and diversity of earlier philosophy of technology was not a mark of theoretical immaturity but was necessitated by the field’s complex subject matter. It is further argued that philosophy of technology should return to its pluralistic role as a meta-analytical structure linking insights from different fields of research. (shrink)

Over the past 40 years a tradition of Marx interpretation has built up around a single passage concerning black slavery in an 1853 letter from Marx to Engels, in order to demonstrate that Marx’s support for emancipation was conditional on the level of ‘civilization’ attained by black slaves. I will argue that this interpretation, which attempts to prove Marx’s racist defense of slavery, is overdetermined by an inattention to historical context and a hypersensitivity to Marx’s nineteenth-century epithets. This is important (...) because the alleged anti-black racism of Marx and the place black workers occupy in his historical materialist vision of class struggle are of the utmost significance for properly conceptualizing the relationship between Marxism and black liberation.

Here I both celebrate and critique the legacy of Charles W. Mills. I begin by offering some reflections on the trajectory of Mills’s career and intellectual development, focusing on his move from Marxist philosophy to the philosophy of race. I then attempt to undermine an argument in Mills’s final book, for why those interested in emancipation should choose liberalism over Marxism. By contrasting Mills with the late Italian Marxist philosopher of history Domenico Losurdo, with whom Mills shared a blistering critique (...) of ‘racial’ liberalism but whom I claim Mills misread, I seek to weaken key premises in Mills’s argument.

Biomarker-based predictive tests for subjectively asymptomatic Alzheimer’s disease (AD) are utilized in research today. Novel applications of artificial intelligence (AI) promise to predict the onset of AD several years in advance without determining biomarker thresholds. Until now, little attention has been paid to the new ethical challenges that AI brings to the early diagnosis in asymptomatic individuals, beyond contributing to research purposes, when we still lack adequate treatment. The aim of this paper is to explore the ethical arguments put forward (...) for AI aided AD prediction in subjectively asymptomatic individuals and their ethical implications. The ethical assessment is based on a systematic literature search. Thematic analysis was conducted inductively of 18 included publications. The ethical framework includes the principles of autonomy, beneficence, non-maleficence, and justice. Reasons for offering predictive tests to asymptomatic individuals are the right to know, a positive balance of the risk-benefit assessment, and the opportunity for future planning. Reasons against are the lack of disease modifying treatment, the accuracy and explicability of AI aided prediction, the right not to know, and threats to social rights. We conclude that there are serious ethical concerns in offering early diagnosis to asymptomatic individuals and the issues raised by the application of AI add to the already known issues. Nevertheless, pre-symptomatic testing should only be offered on request to avoid inflicted harm. We recommend developing training for physicians in communicating AI aided prediction. (shrink)

Surprisingly few articles have focused on Aquinas’s particular conception of necessary beings in the Third Way, and many scholars have espoused inaccurate or incomplete views of that conception. My aim in this paper is both to offer a corrective to some of those views and, more importantly, to provide compelling answers to the following two questions about the necessary beings of the Third Way. First, how exactly does Aquinas conceive of these necessary beings? Second, what does Aquinas seek to accomplish (...) in the third stage of the Third Way? In answering these questions, I challenge prominent contemporary understandings of the necessary beings of the Third Way. (shrink)

To explain the origin of anything, we must be clear about that which we are explaining. There seem to be two main meanings for the term consciousness. One might be called open in that it equates consciousness with awareness and experience and considers rudimentary sensations to have evolved at a specific point in the evolution of increasing complexity. But certainly the foundation for such sensation is a physical body. It is unclear, however, exactly what the physical requirements are for a (...) “central experiencer” to emerge in the course of evolution. Some suggest that it would require a basic brain, others a central nervous system, and others stipulate only a cellular membrane. The open definition is most often assumed by the so-called hard sciences. -/- The closed meaning of consciousness differentiates between a special sort of experience, i.e., conscious experience, and a special sort of awareness (i.e., self-awareness). This is the approach of psychoanalysis and psychology that accepts the existence of an unconscious mind. It is also the view of most phenomenological philosophers and psychologists (Martin Heidegger, Maurice Merleau-Ponty, Jacques Lacan, etc.). This entry discusses several scientific and philosophical views of consciousness and its origins. (shrink)

The purpose of this paper is to show that if one adopts conditional probabilities as the primitive concept of probability, one must deal with the fact that even in very ordinary circumstances at least some probability values may be imprecise, and that some probability questions may fail to have numerically precise answers.

In this paper, I critically evaluate several related, provocative claims made by proponents of data-intensive science and “Big Data” which bear on scientific methodology, especially the claim that scientists will soon no longer have any use for familiar concepts like causation and explanation. After introducing the issue, in Section 2, I elaborate on the alleged changes to scientific method that feature prominently in discussions of Big Data. In Section 3, I argue that these methodological claims are in tension with a (...) prominent account of scientific method, often called “Inference to the Best Explanation”. Later on, in Section 3, I consider an argument against IBE that will be congenial to proponents of Big Data, namely, the argument due to Roche and Sober Analysis, 73:659–668, that “explanatoriness is evidentially irrelevant.” This argument is based on Bayesianism, one of the most prominent general accounts of theory-confirmation. In Section 4, I consider some extant responses to this argument, especially that of Climenhaga Philosophy of Science, 84:359–368,. In Section 5, I argue that Roche and Sober’s argument does not show that explanatory reasoning is dispensable. In Section 6, I argue that there is good reason to think explanatory reasoning will continue to prove indispensable in scientific practice. Drawing on Cicero’s oft-neglected De Divinatione, I formulate what I call the “Ciceronian Causal-nomological Requirement”, which states, roughly, that causal-nomological knowledge is essential for relying on correlations in predictive inference. I defend a version of the CCR by appealing to the challenge of “spurious correlations,” chance correlations which we should not rely upon for predictive inference. In Section 7, I offer some concluding remarks. (shrink)

This thematic bibliography provides a narrative account of the most important literature comprising, and about, the 1930s debates about Christian carried out by Etienne Gilson, Jacques Maritain, Maurice Blondel, Emile Brehier, Gabriel Marcel, and many others.

Throughout his career, Jean-Paul Sartre had a contentious theoretical relationship with psychoanalysis. Nowhere is this more evident than in his criticisms of the concept of the unconscious. For him, the unconscious represents a hidden psychological depth that is anathema to the notion of human freedom. In this paper, I argue that Lacan’s conception of the unconscious-structured-like-a-language overcomes many of Sartre’s most damning objections. I demonstrate that Lacan shares with Sartre a concern to rid the psyche of hidden depths. Both thinkers (...) therefore reject the depth psychological conception of the unconscious and arrive at strikingly similar positions on the nature of the unconscious. In this way, I show that the conceptual analogues that Sartre develops in order to avoid the psychoanalytic unconscious lead him to a position on the unconscious with which Lacan could be in agreement. This indicates that Sartre’s philosophical position is not as at odds with Freudian-Lacanian psychoanalysis as is typically thought. (shrink)

My paper highlights one Personalist aspect of St. Anselm's Platonic perspective, namely the ontological priority and interpenetration of persons. The paper first discusses Anselm's metaphysical Platonism, then charts the Anselmian path towards God, through participation in the divine attributes. It then focuses on images of persons, and their degree of being. I argue that, at least for certain human relationships marked by strong love or friendship, Anselm regards the image of the person as mediating the being of the person imaged.

This paper addresses the generally neglected topic of Vandana Shiva’s ontology. It is argued that there is a significant ontological component to Shiva’s ecofeminist philosophy and that this ontology underpins her ecological and feminist views. Shiva’s ontology provides a standpoint from which she can critique dichotomous ontologies of domination and oppression, and from which she can identify life-sustaining modes of existence. It is argued that this ontology is implicit in most of her works and is best grasped through the analysis (...) of her critique of Western scientific metaphysics. It is further argued that this implied ontology is a continuation of the Hindu-ecofeminist ontology of Prakriti explicitly set forth in Shiva’s Staying Alive (1989). Both forms of Shiva’s ontology, the explicit and the implicit, will be reconstructed and their points of continuity detailed. (shrink)

Williamson has argued against scepticism concerning our metaphysically modal knowledge, by arguing that standard patterns of suppositional reasoning to counterfactual conclusions provide reliable sources of correct ascriptions of possibility and necessity. The paper argues that, while Williamson’s claims relating to necessity may well be right, he has not provided adequate reasons for thinking that the familiar modes of counterfactual reasoning to which he points generalise to provide a decent route to ascriptions of possibility. The paper also explores another path to (...) ascriptions of possibility that may be extracted from Williamson’s ideas, before briefly considering the general status of counterfactual reasoning in relation to our knowledge of possibilities.

(Updated 5/23/24) This unpublished paper, which readers should feel free to cite, is posted primarily for the historical record. In recent work that has, deservedly, received some attention, Paul R. Daniels presents and defends a non-standard theory of persistence that he dubs transdurantism, according to which persisting objects are temporally extended simples. This is exactly what I do in work dating back to Spring 2004. (This work includes this version of this paper, as well as later version that was presented (...) to the University of Rochester's Philosophy Department in 2005.) While this might be a total coincidence, I doubt that it is, especially given that 'transdurantism' appears as a name for a theory of persistence associated with me in at least two places in the literature, one of which includes a citation of this paper. The paper begins with a discussion of what I call 'locative relations' (the relations borne by material objects to the regions of space and time they occupy), which draws relevant distinctions that others have failed to draw. The results of this discussion are then used in constructing spatial analogues for the three established theories of persistence--endurantism, perdurantism, and exdurantism--as well as for transdurantism. Next, these four views concerning persistence are explicitly formulated and a defense of their formulation is offered. Finally, transdurantism's advantages and disadvantages relative to the other theories are discussed. The main goal of the paper is to challenge the trichotomy between the established theories by arguing that transdurantism is also a viable view concerning persistence through time. [Note: Befitting its status as a historical document, with the exception of some light editing to fix typos that might impede understanding, no changes have been made to the paper.]. (shrink)

It seems certain to me that I will die and stay dead. By “I”, I mean me, Greg Nixon, this person, this self-identity. I am so intertwined with the chiasmus of lives, bodies, ecosystems, symbolic intersubjectivity, and life on this particular planet that I cannot imagine this identity continuing alone without them. However, one may survive one’s life by believing in universal awareness, perfection, and the peace that passes all understanding. Perhaps, we bring this back with us to the Source (...) from which we began, changing it, enriching it. Once we have lived – if we don’t choose the eternal silence of oblivion by life denial, vanity, indifference, or simple weariness – the Source learns and we awaken within it. Awareness, consciousness, is universal – it comes with the territory – so maybe you will be one of the few prepared to become unexpectedly enlightened after the loss of body and self. You may discover your own apotheosis – something you always were, but after a lifetime of primate experience, now much more. Since you are of the Source and since you have changed from life experience and yet retained the dream of ultimate awakening, plus you have brought those chaotic emotions and memories back to the Source with you (though no longer yours), your life & memories will have mattered. Those who awaken beyond the death of self will have changed Reality. (shrink)

This paper argues that the recent renewal of interest in the philosophy of Oswald Spengler, particularly concerning its warnings of the imminent demise of Western Civilisation, is misplaced. Arguments concerning the accuracy of his predictions or cultural analysis have overlooked the necessity of evaluating the coherence of the philosophical system that Spengler used to generate and justify his speculative declarations. Such an evaluation indicates a number of apparent contradictions at the heart of Spengler’s historical model. The attempt to resolve these (...) contradictions has resulted in a sharp division of interpretation amongst Spengler commentators, into positivist and relativist camps. Neither interpretation, I suggest, is capable of rendering Spengler’s historical system coherent. It is therefore argued that Spengler’s philosophy is fundamentally flawed. (shrink)

In this paper, I examine Cicero’s oft-neglected De Divinatione, a dialogue investigating the legitimacy of the practice of divination. First, I offer a novel analysis of the main arguments for divination given by Quintus, highlighting the fact that he employs two logically distinct argument forms. Next, I turn to the first of the main arguments against divination given by Marcus. Here I show, with the help of modern probabilistic tools, that Marcus’ skeptical response is far from the decisive, proto-naturalistic assault (...) on superstition that it is sometimes portrayed to be. Then, I offer an extended analysis of the second of the main arguments against divination given by Marcus. Inspired by Marcus’ second main argument, I formulate, explicate, and defend a substantive principle of scientific methodology that I call the “Ciceronian Causal-Nomological Requirement” (CCR). Roughly, this principle states that causal knowledge is essential for relying on correlations in predictive inference. Although I go on to argue that Marcus’ application of the CCR in his debate with Quintus is dialectically inadequate, I conclude that De Divinatione deserves its place in Cicero’s philosophical corpus, and that ultimately, its significance for the history and philosophy of science ought to be recognized.

In this article, I consider an important challenge to the popular theory of scientific inference commonly known as ‘inference to the best explanation’, one that has received scant attention.1 1 The problem is that there exists a wide array of rival models of explanation, thus leaving IBE objectionably indeterminate. First, I briefly introduce IBE. Then, I motivate the problem and offer three potential solutions, the most plausible of which is to adopt a kind of pluralism about the rival models of (...) explanation. However, I argue that how ranking explanations on this pluralistic account of IBE remains obscure and pluralism leads to contradictory results. In light of these objections, I attempt to dissolve the problem by showing why IBE does not require a ‘model’ of explanation and by giving an account of what explanation consists in within the context of IBE.
